Four high-school bishōnen, Kyohei Takano, Takenaga Oda, Yukinojo Toyama, and Ranmaru Morii, have made a deal with their landlady, Mine Nakahara: if they succeeded in transforming her niece into a proper lady they can live in their home rent free, but if they fail the rent will triple. The niece, Sunako Nakahara, is poorly dressed with bad skin and no fashion sense whose bangs cover her eyes. She is also a heartbroken horror-fan who has spent two years as a hikikomori after being told she was ugly when she confessed to her middle-school crush.
